Moves this to be the first check, as it's very simple and fails the registration earlier, instead of potentially initializing the 'indio_dev->label' and checking for duplicate indexes, and then failing with this simple-check. This is a minor optimization, since '__iio_device_register()' will waste fewer validation cycles in case 'indio_dev->info' is NULL. Signed-off-by:

This field doesn't seem used. It seems that only 'buffer->attrs' was ever used to extend sysfs attributes for an IIO buffer. Moving forward, it may not make sense to keep it. This patch removes the field and it's initialization code. Since we want to rework IIO buffer, to be able to add more buffers per IIO device, we will merge [somehow] the 'buffer' & 'scan_elements' groups, and we will continue to add the attributes to the 'buffer' group. Removing it here, will also make the rework here a bit smaller, since this code will not be present. Signed-off-by:

The IIO DMA buffer is a DMA buffer implementation. As such it should include buffer_impl.h rather than buffer.h. The include to buffer.h in buffer-dma.h should be buffer_impl.h so it has access to the struct iio_buffer definition. The code currently only works because all places that use buffer-dma.h include buffer_impl.h before it. The include to buffer.h in industrialio-buffer-dma.c can be removed since those file does not reference any of buffer consumer functions. Signed-off-by:

This change adds the binding doc for the AD9467 ADC. Signed-off-by:

Michael Hennerich authored
The AD9467 is a 16-bit, monolithic, IF sampling analog-to-digital converter (ADC). It is optimized for high performanceover wide bandwidths and ease of use. The product operates at a 250 MSPS conversion rate and is designed for wireless receivers, instrumentation, and test equipment that require a high dynamic range. The ADC requires 1.8 V and 3.3 V power supplies and a low voltage differential input clock for full performance operation. No external reference or driver components are required for many applications. Data outputs are LVDS compatible (ANSI-644 compatible) and include the means to reduce the overall current needed for short trace distances. Since the chip can operate at such high sample-rates (much higher than classical interfaces), it requires that a DMA controller be used to interface directly to the chip and push data into memory. Typically, the AXI ADC IP core is used to interface with it. Datasheet: https://www.analog.com/media/en/technical-documentation/data-sheets/AD9467.pdfSigned-off-by:

This change adds the bindings documentation for the AXI ADC driver. Reviewed-by:
-
Michael Hennerich authored
This change adds support for the Analog Devices Generic AXI ADC IP core. The IP core is used for interfacing with analog-to-digital (ADC) converters that require either a high-speed serial interface (JESD204B/C) or a source synchronous parallel interface (LVDS/CMOS). Usually, some other interface type (i.e SPI) is used as a control interface for the actual ADC, while the IP core (controlled via this driver), will interface to the data-lines of the ADC and handle the streaming of data into memory via DMA. Because of this, the AXI ADC driver needs the other SPI-ADC driver to register with it. The SPI-ADC needs to be register via the SPI framework, while the AXI ADC registers as a platform driver. The two cannot be ordered in a hierarchy as both drivers have their own registers, and trying to organize this [in a hierarchy becomes] problematic when trying to map memory/registers. There are some modes where the AXI ADC can operate as standalone ADC, but those will be implemented at a later point in time.

Currently, when using a 'iio_dmaengine_buffer_alloc()', an matching call to 'iio_dmaengine_buffer_free()' must be made. With this change, this can be avoided by using 'devm_iio_dmaengine_buffer_alloc()'. The buffer will get free'd via the device's devres handling. Signed-off-by:

The 'size_t' type behaves differently on 64-bit architectures, and causes compiler a warning of the sort "format '%u' expects argument of type 'unsigned int', but argument 3 has type 'size_t {aka long unsigned int}'".

This seems like a left-over from a7348347 ("staging:iio: Add polling of events on the ring access chrdev."). Then it was moved into the sca3000 driver around 9dd4694d ("iio: staging: sca3000: hide stufftoread logic"), and that one seemed to be the only user of this. Then it eventually was no longer used after 152a6a88 ("staging:iio:accel:sca3000 move to hybrid hard / soft buffer design.") Signed-off-by:
